Welcome to the "Community.FamilySearch" Forum.
I am just another 'lowly' User/Patron ...
Great suggest enhancement.
You are not alone ...
Many, have been requesting/suggesting such, in the many 'iterations' of the 'FamilySearch' "Feedback" Forums, for, MANY; Many; many, Years.
Some have suggested the 'Term' of, "Archived", rather than "Deleted".
As yet, such has NOT be actioned.
Good Luck, with your suggest enhancement.
Maybe, someone in 'FamilySearch' is listening, this time.
